Feature request: add support for ugrep search engine

[Agron]

Hi,

as a developer I find ugrep to be not only the fastest search engine out there, but it also supports fuzzy search and searching inside documents, pdf files, zip, 7z, and other compressed archives.

I find fuzzy search extremely useful when integrating with new libraries or when I thrown into an existing project.

On the other hand, Krusader search "Feed to Listbox" is fantastic and I use it a lot so that I can list and kdiff3 the files.

All I am asking is when you open the search dialog, on the general tab, can we have an option to pass these search parameters to ugrep (ug), maybe a checkbox next to "Case sensitive (Containing Text Section)" and then capture the list of files ugrep finds?

Best,
